A Kentucky seminary student is missing in Glacier National Park in Montana.  27-year-old Yi-Jien Hwa of Eastern Kentucky went hiking on August 11.

Hwa's family says he was supposed to finish his trip this past Monday, but they have not heard from him.

Searchers have been looking for Hwa since Wednesday, but say they've found no sign of him. 

The search team's commander says they're concerned about Hwa because of the rough terrain, bears and mountain lions, and potential for hypothermia.
